iPhone Duo reportedly has a Shortcuts trigger for opening or closing

MacRumors reports that the iPhone Duo’s “Opened or Closed” Shortcuts trigger appears under Display automations. 9to5Mac says it can run when the phone opens, closes or does either, and describes Stephen Robles using the Open option to launch a productivity app. Switching wallpapers and locking on close are possible uses, not actions shown in that demo; 9to5Mac reports that Robles confirmed the lock option.
